Explanation:
Answer:
x sin nx = x cos nx
same as
theta / theta x (xsin (nx)) = sin (nx) + (nx) cos (nx)
Waxed paper and frosted glass are NOT examples of transparent materials they are however translucent materials. A transparent material is something that you can see through so an example would be water.
